Suggestion for new product direction
As an inveterate listmaker, since the earliest days of the Palm Pilot I have found personal database apps to be among the most useful. Dedicated, non-general-purpose personal database apps fall in three primary categories: security, shopping lists and to-do lists
1Password is unquestionably the ultimate personal security database application, particularly on the Mac platform. Personal database apps in the other two categories are problematic, and even after many years of refinement the ultimate solution remains elusive.
Part of the problem stems from individual customer preferences and valuations of the tradeoffs involved with features and complications that arise from associated feature sets. More than anything else, though, the big problem with personal database apps lies with the difficulty in syncing the apps with their associated host applications.
As Agile is the developer of the most elegant and trouble-free syncing solution for a personal database app in my experience, I implore Agile to consider writing software for these other categories
also. Code that was used for 1Password should be usable for them as well, and since security is much less an issue with them, further development should be much easier than developing for 1Password.
Having tried literally dozens of shopping list apps and dozens of to-do list apps, I know exactly what I want in them, and would be happy to offer suggestions. Individual preferences are highly subjective, however, even if only due to lack of experience—my experience has led me to prefer targeted simplicity over extensive feature sets—and so the key element might be "flexibility." That wouldn't be a difficult thing to implement; it might well be easier than the alternative.
Don't let the fact that there are dozens of these apps out there deter you. It's a testament to the fact that people are frustrated with what exists, and still hungry for better solutions. Even after buying dozens of these apps, I don't forget that I used to pay as much for a year's refill for my DayRunner. Wise people will always seek ways to be more productive, and will be willing to pay to do so.
